TRMM Online Visualization and Analysis System (TOVAS)

warn_icon.gif IMPORTANT MESSAGE Jul 24, 2015    Why do my Data Holdings look different?    

Accessing your data through the GES DISC web site may seem a little unfamiliar to you to these days, but we can assure you, your data is all still available. The location of the data in the online archive has not changed.

The GES DISC has implemented a new interactive interface to make finding data easier than ever. We've added features like searching by keywords, filtering by criteria such as measurements, processing level and spatial resolution, and sortable data columns so now you can fine tune your search results. To get you started we put together a Help document to introduce you to the new interface. If you have any questions about the new design please contact us using the Feedback link in the upper right-hand corner or contact the GES DISC Help Desk by sending email to

The old instances of Giovanni and TOVAS are discontinued.

Please, use the new Giovanni


This is the next generation of the Geospatial Interactive Online Visualization ANd aNalysis Interface (Giovanni 4).  Users can explore and visualize our data in a redesigned interface with improved performance. (Old instances of Giovanni and TOVAS are discontinued)
